Throughout its history, Tesla has always been a company that is looking ahead. Even when the company was hand-assembling tiny volumes of Roadsters, CEO Elon Musk’s “Top Secret Master Plan pointed the way towards lower prices and higher volume. Now, with two vehicles on the market and annual production volumes moving towards the six-figure mark, Musk told analysts on Tesla’s most recent earnings call that lower-cost, higher-volume Model 3 is “overwhelmingly our focus.” As for the Model S and Model X, Tesla’s so-called “Gen 2 vehicles,” Musk says “things feel really quite stable.”

That doesn’t mean that Tesla is done investing in its current lineup, however. In fact, the electric automaker’s latest approved application for sales and use tax exclusion (STE) from the California Alternative Energy and Advanced Transportation Financing Authority (CAEATFA) [PDF of CAEATFA’s staff report here] reveals that it is actually spending nearly half a billion dollars in order to expand the production capacity of its Gen 2 vehicles to 195,000 units per year by approximately 2021.
